Answer:

Step-by-step explanation:
Given 2 similar figures with ratio of sides = a : b, then

ratio of areas = 13² : 17² = 169 : 289 = 
Correct option is B. A discovery in New Jersey actually contributed to the
early economic development of America and, in 1714, a worker uncovered a green rock containing copper.
Here, the use of conjunction 'and' is incorrect as it creates a kind of distortion which seems as if we are talking about two different things: rather then linking the two parts of the sentence, 'and' further disconnects it.
